Circularly polarized luminescence is an important optical property that combines chirality and luminescence in molecular and supramolecular systems. Recently, tunable circularly polarized luminescent supramolecular systems have emerged as promising materials for applications such as smart displays and optical data storage. Non-covalent interactions in supramolecular systems offer various opportunities for regulating circularly polarized luminescence using stimuli, while media modulation methods have been introduced to ensure tunable emission.
Circularly polarized luminescence is an important optical property that combines chirality and luminescence in molecular and supramolecular systems. Recently, tunable circularly polarized luminescent (CPL) supramolecular systems with stimuli- responsiveness have emerged as promising materials for applications including smart displays and optical data storage. Owing to the adaptive capacity of supramolecular systems, intelligent CPL materials have been developed by incorporating chiral and achiral building blocks, thus expanding the available approaches for realizing CPL materials. Non-covalent interactions in supramolecular systems offer various opportunities for regulating CPL emission using stimuli such as light, temperature, pH, mechanical force, electric field, and magnetic field. Several media modulation methods such as host-guest complexation, solvent effect, and gelation have also been introduced to realize tunable CPL emission by ensuring effective chirality transfer, charge transfer, and energy transfer. Herein, recent progress in supramolecular CPL systems regulated using diverse stimuli is presented, and corresponding mechanisms and potential applications are briefly highlighted.
